D-DIMER
D dimer test is carried out to diagnose the intravascular coagulation and fibrinolysis. A negative test indicates that thrombus is absent. However, a positive result does not predict the clot's presence. It indicates the requirement of further diagnostic procedures. This procedure could be CT angiography or ultrasound.
How to prepare for the test?
A clinical brief history should be provided. Also overnight fasting is recommended.
